Specification of Letters Patent.

Application filed March 28, 1910.

Patented Oct. 31, 1911.

Serial No. 552,035.

To all whom it may concern:

Be it known that 1, DAVID LEONARD, a citizen of the United States,residing at St. Louis, in the county of Gratiot and State of Michigan,have invented a new and useful Tile-Machine, of which the following is aspecification.

This invention relates to tile machines.

One of the objects of the invention is to provide simple and improvedmeans for forming tiles without the necessity of tamping the material,whereby to save time and expense.

A further object of the invention is to provide improved means foroperating the core or plunger and for locking the same in raisedposition,

A further object of the invention is to provide an improved form ofhopper for feeding material to the tile jackets.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofthe claims without departing from the spirit of the invention.

In the accompanying drawings forming partof this specificationz-Figure 1is a side elevation of a tile machine constructed in accordance with thepresent invention, the core or plunger, and the operating meanstherefor, being locked in raised position. Fig. 2 is a sectional planview on the line 22 of Fig. 1, looking downward. Fig. 3 is an endelevation, partly in vertical section, of the tile machine with the coreor plunger in lowered position. Fig. 4 is a detail view of the core orplunger.

Like reference numerals indicate corresponding parts in the differentfigures of the drawing. 1

The tile machine of the present invention preferably is constructed witha platform 1 which is supported by means of the legs or supports 2 towhich are secured the lower side boards 3 and the upper side boards 4,the parts thus far described serving to produce a rigid framework.Extending downward through the table or platform 1 are two standards oruprights 5 and 6, that are secured at their lower ends in any suitablemanner to the upper and lower side pieces 4 and 3. Adjacent their upperends, the standards 5 and 6 are rigidly connect-ed with each other bymeans such as the cross piece 7. Secured in any suitable manner to thecross piece 7 is a forwardly extending member 8 the forward end of whichis downwardly bent as indicated at 9 and is formed with a plurality ofratchet teeth or the like 10.

The member 9 constitutes means for holding the operating lever 11 inraised position, such as is shown in Fig. 1, the teeth 10 being adaptedto engage the lower edge of a metal plate 12 which is fixed on the sideof the lever 11 in any suitable manner. The operating lever 11 isprovided with a movable fulcrum which consists preferably of an invertedV-shaped frame 14: the lower ends of which are inwardly bent asindicated at 15, and are pivotally mounted in any suitable manner in theupper side boards 4: as indicated in Fig. 3. The upper or pointed end ofthe inverted V-frame 14: is provided with a cross piece 16 which extendsthrough an eye 17 formed on the upper end of a bolt 18 which extendsvertically through the operating lever 11 and is provided at its lowerend with a nut 19. The frame 14, of course, swings pivotally upon thefulcrum points 15 thereof and thus acts as a movable fulcrum for theoperating lever 11. The function of the operating lever 11 is to raiseand lower the core or plunger 20,-

said core or plunger 20, being secured to the lever 11 by means such asthe inverted V-frame 21 which is secured at its lower end in anysuitable manner to the core 20 and at its upper end is pivotally mountedwithin a slot formed in the lever 11, the connection between the lever11 and the inverted V- frame 21 being a bolt 22 which extendstransversely through the lever.

By reason of the fact that the operating lever 11 is provided with amovable fulcrum, the core or plunger 20 can be moved in a true verticalplane by said lever. The plunger 20 preferably is curved inward orslightly beveled at its lower end as indicated at 24 in order to causeit to penetrate thematerial which is to be molded without the exerciseof a great deal of force on the plunger. In other words by forming thelower end of the plunger so it can be forced into the body of thematerial to be molded, the tile can be properly formed without thenecessity of tamping the material around the core or plunger after saidcore or plunger has been inserted into the jacket or mold.

The means for guiding the core or plunger in its vertical movementpreferably con sists of a rod and guide member which is formed withbifurcated ends 26 which slidably engage the standards or uprights 5,and 6. Adjacent its center, the guide member 25 is enlarged and formedwith a vertically extending opening of a size sufiicient to receive theplunger 20 so as to permit this plunger to slide vertically therein.Adjacent the plunger opening, the guide member 25 is formed or providedwith a plurality of depending lugs 27 which are adapted, when the guidemember is lowered with the plunger, to fit over the upper end of theacket or mold 28 as shown in Fig. 3 whereby to center the plungerproperly therein. The guide member 25 is secured, preferably by means ofthe cords or chains 29 to the pivot member or bolt 22 of the operatinglever 11. The chains 29 have sufficient slack to permit the plunger 20to be almost entirely withdrawn from the jacket 28 during the upwardmovement of the operating lever, before said chains become taut enoughto raise the guide member to the position shown in Fig. l. lVhen theoperating lever is "aised to this latter position, the plate 12 becomesengaged with the teeth 10 of the member 9 and thus holds said operatinglever, plunger and guide member in raised position.

While the parts are in the raised position illustrated in Fig. 1, thematerial from which the tile is to be formed is fed to the jacket 28.The means for facilitating this feeding operation preferably consists ofa funnel shaped hopper 30 which is provided at its lower end with asemicircular flange 31 adapted to contact with the exterior of the upperend of the jacket 98, as shown in Fig. l. The hopper 30 is provided withbrackets 32 which serve to hold in position the circular portion or eye33 of a supporting arm 34 which is pivotally mounted in an eye 35secured in the outer face of the standard 6. hen it is desired to feedmaterial to the jacket 28, the supporting arm 34. is swung inward fromthe position shown in Fig. 3 to that shown in Fig. 1, and is checked inits inward movement by the flange 31. After the jacket has been filledto the desired height, the hopper 30 is swung into the position shown inFig. 3 so as to permit the operating lever 11 and the plunger to belowered during the operation of forming the tile.

The means for holding the jacket 28 in proper position during themolding operation preferably consists of a bar which is Copies of thispatent may be obtained for connected at its ends with the standards 5and 6 and adjacent its center is bent to form an approximatelysemicircular seat 41 which surrounds the jacket 28. lVhen the tile hasbeen properly molded, and the plunger withdrawn upward, the jacket 28 ismoved out of engagement with the seat 41 and the completed tile isremoved therefrom in the usual manner.

hen the acket 28 is in position, the lower end thereof fits in a socket41-5 car ried by a board 47 mounted upon the table 1. For the purpose ofraising the jacket 28 a slight distance so as to cause its lower end tomove out of engagement with the socket 4:5. a lever 4-8 is employed.This lever is suitably journaled on the table 1 and at its lower end asindicated at 4L9 extends through an opening in the table so as to beadapted to raise the jacket 28 when the upper end of the lever isrocked. The lever 48, as shown in Fig. 3,preferablyisjournaled ineye-bolts 50. The shape of the lever 48 is indicated by the dotted linesin Fig. 2.

The tile machine of the present invention is strong, simple, durable andinexpensive in construction, as well as thoroughly etlicient andpractical in operation.

What is claimed as new is 1. In a tile machine, an operating leverprovided with a movable fulcrum, a plunger pivotally connected with thelever, a guide member slidably engaging the plunger, means connectingthe guide member with the lever, a acket arranged to be engaged by theguide member, means for raising and lowering the jacket, and a movablehopper arranged to be moved into and out of engagement with the jacketwhen the lever and plunger are in raised position. 2. In a tile machine,a table, a jacket removably mounted on the table, means engaging thejacket, and a movable hopper arraising the jacket out of engagement withthe last mentioned means, a cross piece having a semi-circular portionengaging the pe riphery of the jacket. an operating lever, a swinginginverted V-frame serving as a fulcrum for the lever, a plate on thelever, a toothed member arranged to engage the plate to hold the leverin raised position. a swinging hopper arranged to fit against the upperend of the jacket, and a plunger connected with the lever and having atapered lower end.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
